Profskrin RC45-1.25 — thixotropic R4 mortar with fine 1.25 mm aggregate
Thixotropic R4 mortar with 1.25 mm aggregate for structural repair of concrete; 20 MPa in 24 hours and 45 MPa in 28 days.

The finishing mortar Profskrin RC40 Sm, based on Portland cement, sand up to 0.63 mm and fibre, reaches at least 20 MPa in compression after 24 hours, 30 MPa after 7 days and 40 MPa after 28 days, with flexural strength from 6 MPa. It is used for structural repair of load-bearing building and bridge structures, treatment and industrial facilities, underground ducts and pipelines. The mix retains workability for 60 minutes, bond to the substrate is from 1.5 MPa, frost resistance at least 300 cycles.
